18QHTF21-10.080-PD

Overview

The 18QHTF21-10.080-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.08 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Selection Notes

Select this component when a precise 10.08 MHz clock source is required with low power consumption capabilities. The LVCMOS output is suitable for interfacing with standard digital logic families. Consider the small form factor for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the intended application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from non-pullable or non-power-down variants in the same family.

Replacement Considerations

Direct replacements must match the 10.08 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical. Cross-reference with other manufacturers offering similar SMD oscillators, ensuring identical mechanical dimensions and functional specifications.
